Quantum mechanics in Dr Who?

One Word Science explains quantum physics in this video using cats, Deal or No Deal and Dr Who:

There are three pretty complicated mathematical rules in there. What you really need to know about quantum mechanics is what those three rules say.

The rules say that very small things, such as atoms and electrons, can theoretically behave as both a wave and a particle. However, if we do an experiment and observe an atom or electron, it then behaves as only one of those things - either a wave or a particle. Until we observe the atom, it could be either - we just don't know!

Remember, a famous physicist said "If you think you understand quantum mechanics, you don't understand quantum mechanics". The extremes of physics are always surprising us. What will quantum mechanics throw up next?
